Newer Blues Artists or Recordings
For some Chicago-style electric blues/jump blues with terrific slide guitar check out: Lil' Ed and the Blues Imperials, "Roughousin'", "What You See is What You Get", "Jump Start". A great band to see live as well. I've seen them three times and... 
Gain and level controls on an amplifier-a good thing?
I think there is nothing wrong with having a volume control, as long the circuit is properly designed. My power amp has one and the manufacturer said some people prefer to not use a preamp, so they are glad to have it. His design is such that if y...

2a3 ?
Loving my Whammerdyne DGA1 amp pushing out just over 4 watts per side, with ultra wide bandwidth transformers (14 Hz - 50k Hz +/- 3 dB). If you are near Atlanta, GA, you are welcome to stop by for a listen.  
Suggestios for Atlanta area brick and mortar
Contact Mike Powell at He carries Playback Designs gear.   
Would you buy a pair of speakers by just looking at the measured freq. response?
No more than I'd  purchase a piece of art based on its written description.   
Extract vocals or instruments from tracks with AI!
Awesome! I would like to run thru all of my many Keith Jarrett recordings and extract all of his distracting whining and moaning. It'd be worth it just for those to me.  
Your greatest high end audio purchase!!!
It’s a tie for me: My PAP Trio15 Horn1 speakers with my Whammerdyne DGA1 amp (4.3 glorious 2A3 watts of sonic beauty).  
Good Speakers for Rock and Roll Under 15K
After hearing Cornwall III and IV I felt they were really great with R&R. Not so much with other genres, but terrific with rock.  
Best Options For A Tubed Preamp - $2500 Or Less, Preferably Used To Maximize Value
Line 2CRM Line Preamplifier from Mapletree Audio - An earlier version has been in my main rig for many years while I upgraded everything else around it. Fun to tube roll to get the sound you prefer.  
What would you do?
Back when I was figuring this out as I was building my system I experienced the most tube sound benefits from the power amp. Every tube piece made an improvement in sound, but for me the amp made the biggest difference.   
***Seasons Greetings A'goners***Are You Getting Any New Gear For Christmas***
Simply one pair of interconnects from Silnote. But that will  complete all ICs being switched over to Silnotes. I am always on an extremely strict budget and as I swapped in each Silnote IC over time the sound became more and more organic, to my l...
